Pheromosa

Pheromosa is an Ultra Beast that resembles a feminine anthropomorphic cockroach. It is primarily white with a rather voluptuous build. Its torso is composed of five thin discs that droop slightly downward. The widest disc makes up its shoulders, the second widest its hips, and the two smallest its chest and waist. There is a gold ovoid inside of the widest disc, where its long, thin neck protrudes from. Its arms and legs are also long, though not quite as thin as usual, with gold joints. Its hands and feet are both composed of two golden claws. Pheromosa has a small, semi-flattened head with a yellow, crown-like structure on top. The two tallest points of the crown point to its long, thin antennae, which are white with small gold balls at the tips. Attached to the back of its head are two structures resembling insect wings. The wings are transparent, curve slightly inward, and reach nearly to the ground. It has narrow, purple eyes with bright blue pupils.

According to Wicke from the Aether Foundation, Pheromosa's curvaceous body is capable of sudden feats of acceleration, able to reach speeds exceeding 120 mph (200 km/h), which no other known life form has previously been able to reach. It also produces a sort of disarming pheromone, which was described as "previously unknown to science" that causes those nearby to become awestruck by its presence. It displays a considerable reluctance towards touching anything as if it interprets the Pokémon world as being unclean somehow. It also seems to have some sort of superiority complex, as it sees itself above everything else -- even other Ultra Beasts.
